Overview

Environment textures depict the view in all directions from a specific point in a scene. In 3D asset rendering, environment textures are the basis for image-based lighting algorithms where surfaces can realistically reflect light from their surroundings. ARKit can generate environment textures during an AR session using camera imagery, allowing SceneKit or a custom rendering engine to provide realistic image-based lighting for virtual objects in your AR experience.

In both cases, ARKit automatically generates environment textures as the session collects camera imagery. Use a delegate method such as session(_:didUpdate:) to find out when a texture is available, and access it from the anchor's environmentTexture property.
